Book review: bash Cookbook

Filed under
Reviews

One of the reasons I love cookbooks, of all kinds, is because cookbooks have a clarity and simplicity of purpose. Whether it’s a cookbook for code geeks or for food geeks, its raison d’etre is the same: the “cook” has a job to do, and not a lot of time to do it. If a home chef wants to whip up a nice dinner for guests, he don’t want to have to understand the entire history of French cooking; he just wants a simple, well-written recipe for coq au vin. Similarly, if a sysadmin wants to receive an hourly email with a list of zombie processes on the new test server down the hall, she probably wants to hack together a quick bash script, and she doesn’t want to read the collected works of Grady Booch to do it.

Therefore, for me, the best benchmark of a code cookbook is how effectively I can go from the idea, “I need a script to do ‘foo’,” to having a script that does “foo” effectively. It was with this purpose in mind that I set O’Reilly’s new bash cookbook down next to me.

From the Editors: You’ve come a long way, Linux

This month, as we do every March, we reported on the Who Writes Linux report from the Linux Foundation. Usually, this is a fairly rote affair: Red Hat and Intel contribute tons of code, Greg Kroah-Hartman does a ton of the work, and we learn about some small firm somewhere that’s cranking out kernel code disproportionate to its size.

Understanding The Linux Kernel's BPF In-Kernel Virtual Machine

BPF continues marching forward as a universal, in-kernel virtual machine for the Linux kernel. The Berkeley Packet Filter was originally designed for network packet filtering but has since been extended as eBPF to support other non-network subsystems via the bpf syscall. Here's some more details on this in-kernel virtual machine. Alexei Starovoitov presented at last month's Linux Foundation Collaboration Summit in Santa Rosa about BPF as an in-kernel virtual machine. The slides have been published for those wishing to learn more about its state and capabilities. Read more
